MEANS FOR DELIVERING CUT GRAIN FROM A HARVESTER TO A BINDER Filed Aug. 7, 1955 Fig.1.

3nventor WaZzr Vl/ZRu'sseZZ,

Patented Apr. 21, 1936 UNHTED STATES A N OFFICE MEANS FOR DELIVERING our GRAIN FROM A HABVESTER To A BINDER My invention relates to improvements in communicating mechanisms between a harvesterand a binder, and an object of my improvements is to provide a simplified, relatively inexpensive and convenient means for carrying out grain from the one to the other.

Another object of my improvements is to indude in this carrying mechanism devices for engaging and propelling by a step bystep action cut gra n in parcels fromthe harvester to a binder.

Another object of my improvements is to associate with such step by step propelling means auxiliary devices at the beginning and end of the same for initiating the above functions to the point of action of a binding mechanism upon the successive parcels of cut grain delivered to it. I have accomplished the above objects by the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawing.

' Fig. 1 is a rear elevation of my said mechanism as associated operatively with parts of a harvester 'and a binder, only certain coacting elements of which are shown inuse with my said mechanism.

Fig. 2 is a detail top plan of a binder needle in association with the mechanism which is employed by a step'by step movement in passing on cut grain into the scope of action of a binder.

.- The mechanism of many such delivery mechanisms is often verycomplicated and of costly construction, and my apparatus for this purpose may be easily associated with the cutting and delivery mechanism of a harvester, to receive the cut grain therefrom and supply it in parcels to the binding and knotting mechanism of harvesters.

The figures of the drawing are diagrammatic in character for convenience, and it is obvious that various changes may be effected in the different features and elements of my apparatus without departing from my invention or the scope of protection thereof as stated in the accompanying claims.

The numeral l denotes the extended platform of a harvester as seen from the rear, and on this is mounted a rotary shaft 3 carrying an endless belt 4 and rotated by any convenient connection to the harvester mechanism not shown. On a sprocket wheel not shown on the farther end of the shaft 3 is carried a sprocket chain 5. Forward of the shaft 3 posts or other supporting means Ill carry in bearings a crank-shaft l I having a pair of oppositely directed cranks l2 and I3 thereon intermediate the posts. On one end of ing upwardly andforwardly relative to the adjacent end of the traveling apron 2 to receive cut arm 33.-34.

the crank-shaft II is a sprocket wheel 43 carrying theforward part of the chain 5. Between the shafts 3 and H a horizontal shaft 1 is supported .in bearings in spaced posts and carries a plurality of separated star-wheel teeth 8, while on the 5 front end of the shaft 1 is mounted a sprocket wheel 6 between and engaged by the sprocket chain 5 as shown in said Fig. 1. The numeral 9 denotes a fixed and inclined runway deck extenda grain from the latter.

On any suitable fixed support or brackets 44 depending fromthe farther end of the deck 9 on a pivot shaft 3| is mounted abinder needle 35 of .a well known type, by means of a medial The apertured point of the needle is above and a little forwardly of said shaft II, when in it's lowered position beneath said deck.

Above. this needle and the deck 9 on a fixed standard 21 or other supporting means is mounted a rotary shaft 22 carrying a packer wheel 2| from whichprojects a packer arm 23 radially. On the shaft. 22 is also mounted a cam 24 having an edge notchwith which a traveler wheel 25 on a movable rod 26, being elements of a binder mechanism, is in contact alongthe rim of the cam and at times locked releasably in its notch. Other features of the binder and knotter means are not shown, not being included in my invention.

. On the'forward face of the packer wheel 20 are bevel gearteeth 2| engaged by a bevel pinion l9'on an upright shaft IS, the lower end of the shaft carrying a bevel pinion IT in mesh with a bevel pinion l6 fixed on the crank-shaft H, but not shown in Fig. 2.

On the crank-pins of the cranks 38 and 39 are pivotally mounted the grain propeller arms 36 and 3! of the same shape and dimensions and having forwardly concaved finger parts 41. These arms are spaced apart circumferentially on the shaft l I, and to traverse, as do certain elements 8 and 35, a longitudinal slot in the deck 9.

On pivots as at 40 on the brackets 44 are pivoted the forward ends of swingable rods 38 and 39 respectively, and whose rear ends are pivoted as at 46 to the shanks of said arms 36 and 31. An arm 32 projects from the pivot 3| and is pivotally connected to an upright member 29 which carries a link having a pivotal connection at with the packer wheel 20. By this means the needle member 33 is rocked to and fro, to cooperate with a binder and knotter not shown, in the binding and securing of twine about parcels of cut grain which are propelled in succession up the deck by means of the fingers 41 of the arms 36 and 31 in turn. The numeral 28 denotes a forward supporting arm mounted to reciprocate at times to close the forward end of the deck 9 to serve as a stop for a parcel of cut grain propelled forwardly by one of said arms 36 or 31, and to hold the parcel while being twined and knotted, but the mechanism for actuating the arm 28 is not shown, being old in this art.

Operaticm.Cut grain is; deliveredfrom the traveling apron 2, where it is picked up by the star-wheels 8 which move it forwardly intos the 3! as they are oscillated "in turn-Ion. the crankpins 45 by rotation of the shaft I l, as limited by the scope of movements of the swinging-arm's and 39.

In synchronism the shaft" and packer wheel 20 are rotated by the shaft H. A iquantityiof grain propelled forwardly by. one of the arms. or 31 into the sphere of action of'the ,nee'dle'33, is shapedinto a'parcel bythe rotating arm'if23 on the packer wheel -20,"th,e latter :drivenby' the crank-shaft ll through the mediumbf the shaft l8 and its end gearingslfi and; I], andi'l9 respectively,-where-the'parcel is tied into a'gshe'af by the rising and rocking needle 33, as held by the 'rockable arm 28, on thejdeck 9,-and. cooperating binding and knottingdevicesnot here illustrated.

When the sheaf'thus' formed and tied after recession of the respective pusher arm736or3'l; and separation of the tying twine at the-knottenthe arm -28 recedes to clear the sheaf which is discharged from the deck 'by the rotating. arm "23.

The arms '36 and 3'l-inturn rismpsnetrategrain on'the deck 9,'carry it'forward past-"the needle 33 which is in its downward position; and which then risesto string the 'parcelin a'sheafin, the usual way. The arms 36--- and"31 sink: successively "through the deck opening so-that thei'arms move through the deck-substantially ,upwardly and downwardly and so as toleastobstructthe passing grain during said-operationsf'lhe invention herein therefore relates to the means" used for transferring the cut grain from the' traveling apron 2 to deliver it within 'the scope of action 'of the' needle' 33 and other devices for, binding, *knotting and severing the binding twine before the-bound sheaf is expelled-by'thearmil as'the otherarm-28 subsides below thelevelof the deck.

It is therefore important in my invention to supply-mechanism of an intermediate character to satisfactorilyperform the above functions,

while by the simplest and cheapest means, for economy, lightness of the assemblage and ease of action in practice.

I claim:

1. A carrying mechanism positioned to receive cut grain and transport it in parcels to a binder, comprising the combination with an apertured upwardly inclined deck, of a rotatable shaft beneath the deck, having cranks thereon, arms .rockably mounted on the cranks and having terminals-protrusible successively in turn upwardly through the apertured deck and then recede xwholly below the deck in alternation to penetrate paths of action of the step by. step arms. and
